lMPROVEMENT IN CHURN-POWERS.

Specification forming part of'Lettel's Patent No. 40,751 dated December 1, 1863.

To aZZ whom it may concern.-

Be it known that I, ELIHU Hone, of Itensselaerville, in the county of Albany and State of New York, have invented a new and improved Churn-Power, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side sectional view of my invention, taken in the line 00 m, Fig. 2 Fig. 2, a front view of the same; Fig. 3, an enlarged detached view of the escapement pertaining to the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and improved churn-power of that class in which a weight or spring is used as a motor.

The object of the invention is to obtain a much simpler 1 device than those previously devised for the purpose, and one which may be economically constructed and be compact or occupy but a limited space.

The invention consists in the manner of applying the power to the churndash, which is of the reciprocating kind, whereby the use of a crank and other working parts are dispensed with.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a framing, which may be constructed in any proper manner, to support the working parts of the device; and B is a drum, which is placed on a shaft, 0, in the upper part of the framing. may, if desired, be of wood, and both turned out of a single piece.

D is a shaft, which is placed in the framing A some distance below the drum B, and has a toothed wheel, E, at one end of it. This toothed wheel gears into a pinion, F, on a shaft, G, which is just below the shaft D, and on the shaft G adjoining the pinion Fthere is placed loosely a scape-whee1, H, the latter having a pawl, a, attached to it, which is kept engaged with the pinion F by means of a spring, I). (See Figs. .1 and 3.) This pawl admits of the pinion F turning the scapewheel when the former is rotating in the direction indicated by the arrow 1. One end This drum and its shaft of the shaft G projects through the side of the framing A, and has a square, 0, formed on it to receive a key.

I is a cord or chain, wh ch is attached to the shaft 0, and has a weight, J, suspended to it. This weight may be constructed of a box havin g stones or other substances placed in it so as to increase or diminish the weight as occasion may require. To the drum B there is attached a cord or chain, K, which is also attached to the shaft D.

L is a rock-shaft having two arms, (1 d, att ched to it. These arms project a short distance above the shaft L and extend down at a greater distance below it, and are secured to a box, M, which may contain a greater or less quantity of stones or other substances to give it the requisite weight. To the upper end of one of these arms, (1, a rod, N, is attached, the front end of which is connected to the upper end of'a bent lever, O, the fulcrum e of which is in the upper end of an upright, P. The other end of the lever O is connected to the churn-dash Q. The other arm, at, has two pawls, f f attached to it, one pawl, f, being above the rock-shaft I, and the other, f, below it. (See Figs. 1 and 3.) The lower pawl, f, is rather longer than the upper one, f, and the lower one, f, has a semicircular projeetion, g, at its under side near its front end, and has an inclined curved surface, h, at its upper side and at its front end, as shown more particularly in Fig. 3. The upper pawl,f, has its under surface near its front end curved, as shown at i.

From the above description it will be seen that when the weight J is wound up motion will be communicated to the shaft D in the direction indicated by the arrow 2, and motion communicated to the shaft G from D through the medium of the gearing EF. The scape-wheel H acts alternately against the two pawls f f and communicates from the rotat-ing shaft G a rocking movement to the shaft L, and consequently an oscillating movement to the arms at d and box M, the arm at communicating, through the medium of the rod Nand bent lever 0, an up-and-down movement to the churn-dash Q. The pawlf is thrown in contact with the scape-wheel H, as it approaches it, in consequence of the projection 9 at its under side working over a projection, 9" Q n attached to the fran'iing, and the pawl fis throw m with,

the scape-wheel in consequence of moving over the inclined curved surface h on then-p per side of the pawl f. By this arrangement it will be seen that the'power is appliedto the churn-dash Q in a very direct manner, cranks are avoided, and the orkingparts reduced to a small number.

I would remark that a spring might be used as a motor instead of the weight J; but as Weight I consider preferable.

Having thus described my invention, What" i i
